Hi all

Getting a T120 bitsa back together for off road racing and scrambles riding.

Has anyone removed a Brit twin flywheel and run it? I wanted to know if there are any issues experienced that I can not foresee. At this time it looks really straight forward.
remove > re-balance > do wheelies> get chicks

I am interested in deleting the flywheel altogether. I have been lucky enough to have done this in many a different racing disciplines from dirt bikes to sprint car racing. We added weight for road and drag racing. I appreciate the willingness for insight on the hypothesis, but I am really just interested in first hand experience. Thanks for understanding.

Did any of you find a detrimental flaw to this idea? Broken parts etc?

Thanks for your help

If it has 2 wheels I might need it.

Some trailbikes have an external flywheel (inside covers, easy to remove)( but not british.)
I know someone who removed it, same goals.

Made it more like a 2 stroke than a 2 stroke !
10,000+ rpms at the mere flick of the wrist.

But, what TT said.
Soon as the rpms got low-ish, just stopped dead in its tracks.

It was fun while you could keep it going though....

Yeah
I assumed it may be a bit frustrating. I may give it a shot to see. This is my bitsa bike. It’s well adjusted to quick tear down
